The user setting to disable Reference Previews is still set up in the Page-Previews codebase. This needs to move. See [1]
- Copy the code creating the user setting over to the Cite extension
- Make sure to also include the i18n messages involved and see for example T363156: Move ReferencePreviews i18n messages from Popups to Cite
- Make sure that we do not end up in having two settings for the same thing added
- After the changes in Cite are fully deployed remove the settings setup from the Popups codebase
